DESCRIPTION
The Texas Instruments LMX9838 Bluetooth Serial
Port module is a fully integrated Bluetooth 2.0
baseband controller, 2.4 GHz radio, crystal, antenna,
LDO and discreets; combined to form a complete
small form factor (10 mm x 17 mm x 2.0 mm)
Bluetooth node.
All hardware and firmware is included to provide a
complete solution from antenna through the complete
lower and upper layers of the Bluetooth stack, up to
the application including the Generic Access Profile
(GAP), the Service Discovery Application Profile
(SDAP), and the Serial Port Profile (SPP). The
module includes a configurable service database to
fulfil service requests for additional profiles on the
host. Moreover, the LMX9838 is qualified as a
Bluetooth endproduct, ready to be used in the end
application without additional testing and license cost.
Based on TI’s CompactRISC 16-bit processor
architecture and Digital Smart Radio technology, the
LMX9838 is optimized to handle the data and link
management processing requirements of a Bluetooth
node.
The firmware supplied in the on-chip ROM memory
offers a complete Bluetooth (v2.0) stack including
profiles and command interface. This firmware
features point-to-point and point-to-multipoint link
management supporting data rates up to the
theoretical maximum over RFComm of 704 kbps. The
internal memory supports up to 7 active Bluetooth
data links and one active SCO link.
The on-chip Patch RAM provided for lowest cost and
risk, allows the flexibility of firmware upgrade.
The module is lead free and RoHS (Restriction of
Hazardous Substances) compliant. For more

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
